Simulation for Improving the Performance of Small and Medium Sized Enterprises

Abstract

The success of small and medium enterprises to adapt to constant changes in the environment largely depends on the different strategies and management decisions taken by managers at the operational level. This paper is searching for a tool that would allow managers at all levels to consider the effects of their decisions on the success of the enterprise as a whole. In this sense, the application of system dynamics developed one modular simulation model of business processes of SMEs. Developed model recognizes the specificities of SMEs, such as a large range of products, the use of a wide variety of materials, production in small batches and requests for reduction of lead time (Lead Time). The effects of various strategies and management decisions can be observed by monitoring the dependence of performance measures of simulated process on values of model parameters. Through four experiments the effects of changes in inventory management policies, the availability and size of the lot were simulated. The results of experiments showed that the variation of the model parameters should be oriented simultaneously towards several of the aforementioned directions.

Autonomous Robotic Inspection System for Drill Holes Tilt: Feasibility and Development by Advanced Simulation and Real Testing

“…With rapid developments in technology, simulation software used to evaluate a robotic system has reached adequate potential. This enables a company to examine the potential of a robotic system before attempting a major change in the factory line [6], [7]. In a standard inspection process, a robotic system is an accurate, cost and time effective approach than conventional processes [8].…”
